descriptiondrygres drill bits are the best solution for users who want to drill holes of various sizes in all types of tiles.drygres drill bits are ideal for drilling stoneware porcelain stoneware granite and marble.the diamond in drygres drill bits is applied using vacuum soldering technology which increases their resistance to high temperatures and friction.rubi offers different kits tailored to the needs of every tiler.drygres drill bit kits allow for the professional preparation of holes for water installations drains electrical boxes etc.the drygres kit consists of:- multidrill guide- diamond drill bits for dry cutting of 28 35 43 and 65 mm diameter (ref. 06967)- diamond drill bits for dry cutting of 28 35 43 and 65 mm diameter 28 35 43 50 and 65 mm (ref. 06968)- diamond drill bits for dry work ø 6 8 20 35 50 and 68 mm (ref. 06969)- diamond drill bits for dry work ø 6 (x2) 20 and 35 mm and a tcr-115 superpro diamond disc (ref. 68923)- casesdrygres drill bits thanks to the m14 thread can be used directly on a grinder or thanks to the adapter (ref. 05976) on a drill without impact.the average durability of drygres 20-75 mm cores is 60 holes and always depends on the type of material and its thickness as well as proper cooling and use.drills drygres drill bits can drill holes up to 36 mm deep.the side hole in drygres 20-75 mm drill bits allows for better cooling and removal of debris after each hole is drilled.remember to clean and inspect the drill bit before each drilling operation.the maximum operating speed of the drill bit is 14000 rpm.to ensure a good hole finish and the durability of the drill bit do not exceed the specified speeds.it is also recommended to move the drill in a circular motion for better cooling.
